Action of Oil-eating Microbes Challenged in Arctic Seas

Researchers at Arctic Research Centre of University of Aarhus have come up with the first assessment of causes of microbial degradation in seawaters off Greenland. These researchers have identified six factors challenging microbial action in Arctic seas.

With new economic developments such as oil exploration activities and trans-Arctic shipping, the Arctic is posed to unprecedented risk of marine oil spills. This calls for thorough understanding of the adaptability and self-cleaning capability of Arctic ecosystems to weather from marine oil spills.
While extensive efforts are undertaken to clean large oil spills, mechanical methods employed are effective to clean up only 15 to 25% of oil. This has been ascertained in major oil spills such as the one in Deepwater Horizon in the Gulf of Mexico and Exxon Valdez in Alaska’s Prince William Sound. In these oil disasters, oil-feeding microbes played a pivotal role in degrading the oil and lowering the impact of spilled oil.

Cold Temperatures Prevent Oil Dispersion to hamper Microbial Action

As a matter of fact, low temperatures affects by altering spilled oil’s chemical properties and slows down biodegradation. Cold oil, for example, is more viscous that hampers oil dispersion. Such conditions of non-dispersion of oil in small droplets decreases efficiency of microbial degradation. Waves also play a pivotal role to break oil into small droplets. However, presence of sea ice makes for less or no waves.

The Arctic ecosystem generally contains very low concentration of nutrients such as phosphorus and nitrogen. Oil does not contain these nutrients, therefore oil-feeding bacteria need to find them in water. On the other hand, some nutrients result in lowering action of oil-feeding bacteria.

Rising Cases of Organ Damage to Drive Global Perfusion Systems Market

San Francisco, California, February 22, 2018: A recent market research report by TMR Research provides a wide coverage of the global market for perfusion systems, its present state of development, historical growth trajectory, and forecasts pertaining to its growth prospects over the period between 2017 and 2025. The report is titled “Perfusion Systems Market – Global Industry Analysis, Size, Share, Trends, Analysis, Growth, and Forecast 2017–2025.”

One of the key factors spelling growth for the global perfusion system market is the massive rise in rate of prevalence of a number of chronic diseases, which often lead to organ damage and lead to the necessity to transplant organs. Moreover, factors such as alcohol consumption, smoking, improper diets, and ignorance regarding a healthy lifestyle are also leading to a vast rise in cases of organ damage, leading to the increased need for organ transplants and driving the global perfusion systems market. These factors are expected to continue to drive the global perfusion systems market in the next few years as well.

Organ transplant is presently the only treatment effective in cases of organ failure in the critical stages. Owing to technological advancements, the rate of successful organ transplants has gone massively up and is having a positive implication on the overall development of the global perfusion systems market. The lack of organ donor and strict regulations against paid organ donations, on the other hand, continues to hinder the overall pace of development of the global perfusion systems market. While a large number of people across the globe register for organ donation every year, only a few actually donate their organs. Attempts at raising awareness among consumers in this regards could auger well for the market.

Geographically, the report states that the market in North America is presently the most promising regional market owing to the rising demand for cardiothoracic and organ transplant surgeries. The large number of number of government initiatives aimed at raising awareness regarding organ donation in countries such as Canada and the U.S. is further expected to provide promising growth avenues to the perfusion systems market in the region in the next few years.

While the market can benefit from vast untapped growth opportunities in emerging economies such as Asia Pacific and Latin America owing to the vast rise in cases of organ damage and rising awareness regarding available treatments, the high cost of these surgeries is arresting the growth of the market.

The research report provides a comprehensive coverage of the competitive landscape of the global perfusion systems market and the companies operating within it. The strategic evaluation of the competitive landscape allows clients to make well-informed and calculated decisions. The report also summarizes the overall performance of the companies during the forecast period and offers insightful suggestions to improve businesses at various levels. The key recent mergers and acquisitions are highlighted and equal importance is given to product development and innovation. With the help of current and projected statistics, sector- and region-wise company shares are presented and analyzed.

Some of the leading companies operating in the global perfusion systems market are Lifeline Scientific, Inc., Medtronic plc, ALA Scientific Instruments, XENIOS AG, LivaNova PLC, Spectrum Laboratories, Inc., XVIVO Perfusion AB, Repligen Corporation, Getinge AB, Harvard Bioscience, Inc., Terumo Corporation, and Merck KGaA.
